G&W Electric LPP joints rated up to 345kV are designed for pipe-type high pressure fluid filled (HPFF), 3-core cables with laminated polypropylene paper (LPP) or paper insulation, handling rated fluid-filled pressures up to 400 psi.
Features and Benefits
The joint features a field-machined (FM) connector and a field-applied, LPP/paper-insulated body, including cable insulation “stepping” at the connector and stress control slopes at ground electrodes.
Every joint is custom designed and engineered for the specific cable system requirements and field constraints.
The 345kV-rated joint can fit in a typical 18’x6′ manhole.
All necessary construction materials and parts are supplied with each kit, including tapes, carbon steel casings, reducers and cable supports (spiders).
The joint is qualified per IEEE 404-12 at 345kV system voltage level.
